Abstract

A self-powered self-induction magneto-rheological damper, including a connecting rod, an upper end cover, a stator, a first guide sleeve, a magnetic pole, a permanent magnet, an electromagnetic coil, a piston rod, a connecting end cover, a second guide sleeve, a seal, and a cylinder Body, piston with coil, bottom end cover, charge signal line, bottom earring, piezoelectric electrode, piezoelectric sheet, rubber sheet, air bag, wire and electric energy signal control module. The invention can adjust the size of the output damping force in real time according to the size of the external vibration force, thereby realizing the intelligent closed-loop control of the external vibration. The structural vibration control system based on the self-powered self-induction magneto-rheological damper will become very simple and greatly reduce the application cost because it does not require additional power input equipment and external vibration force test equipment, and is especially suitable for Applications where space is limited and power supply is inconvenient, such as: large buildings and bridges, etc.

Description

technical field [0001] The invention relates to a semi-active magnetorheological vibration control technology, specifically a self-powered self-induction magnetorheological damper. Background technique [0002] The magnetorheological damper is a semi-active control damper with smart material magnetorheological fluid as the working medium. By controlling the input current, the strength of the electromagnetic field loaded on the magnetorheological fluid is changed, and then it can be Within tens of milliseconds, the rheological properties of magnetorheological fluid change, realizing the transition between fluid and semi-solid, thus providing controllable damping force. Compared with conventional hydraulic dampers, magnetorheological dampers have the advantages of small size, simple structure, large damping force, wide dynamic range, and low power consumption. Tonality is gradually being applied to vibration control in automotive engineering, construction engineering, aerospa...
